trust-store-sk using alot of CPU

I originally want to report it as a bug but maybe it`s a know issue that can be solve somehow so i decided to ask first...

It seems that for some reason trust-store-sk process is using alot of CPU is that expected? is there a solution?

Only noticed it happening twice but I think it happen before (by the battery depletion rate ) , It seems that some times the trust-store-sk process can use a lot of the cpu time (around 150-200%) for a long time (timed it to over an hour and still going...). this causes fast battery depletion on ubuntu mobile devices.

Probable cause :

This seems to appear when a web app crashes. it happen twice when 'reddit mobile' crashed.
I will investigate it further and will update this issue if I`ll be able to find the actual cause.
